You are qualified for a commissions depending on what the amount of product you purchased. You will receive corresponding commissions for all programs priced up to the amount of package you sign up.
For example: You bought a $15k program and you promote a $35k program. So if someone buys a $35,000 program, you will not receive any commissions for that because you are not qualified for that level. That commissions will roll over to the person above you who is positioned at the $35,000 level. However if someone buys say, a $15,000 or $10,000 or $5000 package and below, you are eligible to receive commissions on all that.
